Plaster/Fiberglass Casts and Splints:

1. Elevate the extremity above the level of the heart as often as you can, to reduce swelling.

2. Check for adequate circulation by briefly depressing nail beds or the tip of the fingers or toes. The skin will blanch, and then should return to normal color quickly after releasing pressure. Call the doctor’s office if poor circulation is noted or not improved with rest or elevation above the level of your heart. Persistent tingling, numbness, and pain should also be reported as this may be a sign of poor circulation or poor skin condition inside the cast.

3. Keep your splint or cast dry. Moisture weakens plaster and damp padding next to the skin can cause irritation. Use two layers of plastic or purchase waterproof shields at a pharmacy to keep your splint or cast dry while you shower or bathe.

4. If the skin under a cast or splint begins to itch, do not stick anything inside to scratch, as the skin may easily tear and become infected, which can then cause complications for healing.

5. Do not engage in vigorous activity involving the cast area.

6. Do not pull out or rearrange the cast/splint padding.

7. Do not try to trim or cut off the cast/splint.

8. Avoid dirt. Keep dirt, sand, and powder away from the inside of your splint or cast.

9. Call our office if your cast/splint becomes too loose, or if it develops any cracks or soft spots.

10. After leaving our office, allow several additional hours for the cast or splint to fully dry before pressing or leaning on it in order to avoid creating a dent or pressure area inside the device.
